configure: Support configuring C++ compiler
Add configuration for C++ compiler in configure and Makefiles.
The C++ compiler is choosed as following:
- ${CXX}, if it is specified.
- ${cross_prefix}g++, if ${cross_prefix} is specified.
- Otherwise, c++ is used.
Currently, usage of C++ language is only for access to Windows VSS
using COM+ services in qemu-guest-agent for Windows.
